Our proposed innovation is to design and fabricate a diode pumped Er:YAG micro-chip laser capable of varied repetition rates and high pulse energies using the single emitter-based high brightness pump developed in the Phase I. Future NASA missions will require high-pulse power with variable repetition rate flash and scanning LIDAR systems. Such LIDAR systems offer the advantages of excellent spatial resolution, high efficiency, and high beam quality. We propose to design and fabricate a resonantly pumped, passively Q-switched Er:YAG laser for eye-safe wavelength operation. We will incorporate the Er:YAG crystal and saturable absorber into the pump module, creating a compact, robust, and efficient Q-switched solid-state microchip laser.
